• All EQ controls throughout the sound system should be set flat before setting
up the FDS-310 LEVEL controls. Any house EQ adjustments can be made
later.
• For a 3-way set up, set the MID RANGE control first for a comfortable level.
Then bring up the LOW RANGE control until the music/vocals/speech is
'filled-out'. Next, increase the HIGH RANGE control until the vocals have a
natural presence. Finally, you may want to readjust the LOW RANGE for the
best balance.
• Where ever possible, note the LEVEL control settings and then challenge
your colleague(s) to repeat the set up, from scratch. Compare your settings,
and try to arrive at a 'best fit' if your ears disagree.
MUTE switch
18.0 Using the Mute switch
Each frequency bands' control surface includes a MUTE switch (See Figure
6.1). Depressing it silences the output in question. The associated PEAK and
SIGNAL LEDs remain in operation. Push button muting is an invaluable
facility when setting up, otherwise the LEVEL controls would need to be reset
to -00.
